When listing  the  default and available ciphers  with  8u202  (testcase listed below)  One can notice that TLS_EMPTY_RENEGOTIATION_INFO_SCSV is gone. With 8u192 it was still in the list of default and available ciphers.

It appears, "8211883: Disable anon and NULL cipher suites" is the reason TLS_EMPTY_RENEGOTIATION_INFO_SCSV is gone now.

It looks like some of our Tomcat users are running into this issue because  
TLS_EMPTY_RENEGOTIATION_INFO_SCSV   plays some role  there .

Testcase & Reproduction Instructions
import java.util.*;
import javax.net.ssl.SSLServerSocketFactory;
public class Ciphers
    public static void main(String[] args)
        throws Exception
        SSLServerSocketFactory ssf =
        String[] defaultCiphers = ssf.getDefaultCipherSuites();
        String[] availableCiphers = ssf.getSupportedCipherSuites();
        System.out.println("default ciphers:");
        for (String s: defaultCiphers) {
        System.out.println("available ciphers:");
        for (String s: availableCiphers) {
            System.out.println("available:" + s);

Fix request: This is an important fix for a regression which needs to go to JDK 11 updates. The patch applied cleanly but the test case had to be modified a little to make it succeed in the JDK11 environment.
